Essentially, the Spring Boot Actuator can be considered a subproject of Spring Boot. It helps bring production-grade features in the application that we develop using Spring Boot out of the box. The Spring Boot Actuator needs to be configured before we can leverage the features exposed by it. The Spring Boot Actuator has been available since Spring Boot first release in April 2014. The Spring Boot Actuator materializes different HTTP endpoints so the development team can perform the following tasks:

• Application monitoring
• Analyzing application metrics
• Interacting with the application
• Version information
• Logger details
• Bean details
